Thank you for reaching out. We are aware of resource utilisation problems on SCB hosts. After the incident, we have limited the amount of memory the PDF rendering service can use~[1]. However, it is important to note that most of the time ORES is the service using most of the resources on these machines, and they are shared amongst 9 different services. In light of that fact, we have previously recommended commissioning a separate cluster for ORES. As far as I know, the budget should be there and it should be implemented in FY 2017/2018, but will let Aaron correct me here in case I'm wrong :)

Cheers,
